MapEventType

MapEventType = object

MapEventType - a mapping between the event name and the event value. These events are used with the Map.on method. When using a layerId with Map.on method, please refer to MapLayerEventType. The following example can be used for all the events.

Example

// Initialize the map
let map = new Map({ // map options });
// Set an event listener
map.on('the-event-name', () => {
  console.log('An event has occurred!');
});

Properties

boxzoomcancel

boxzoomcancel: MapBoxZoomEvent

Fired when the user cancels a "box zoom" interaction, or when the bounding box does not meet the minimum size threshold. See BoxZoomHandler.

click

click: MapMouseEvent

Fired when a pointing device (usually a mouse) is pressed and released at the same point on the map.

See

• Measure distances
• Center the map on a clicked symbol

dataabort

dataabort: MapSourceDataEvent

Fired when a request for one of the map's sources' tiles or data is aborted.

dataloading

dataloading: MapSourceDataEvent | MapStyleDataEvent

Fired when any map data (style, source, tile, etc) begins loading or changing asynchronously. All dataloading events are followed by a data, dataabort or error event.

dblclick

dblclick: MapMouseEvent

dragend: MapMovementEvent

Fired when a "drag to pan" interaction ends. See DragPanHandler.

See

Create a draggable marker

dragstart

dragstart: MapMovementEvent

Fired when a "drag to pan" interaction starts. See DragPanHandler.

error

error: ErrorEvent

Fired when an error occurs. This is GL JS's primary error reporting mechanism. We use an event instead of throw to better accommodate asynchronous operations. If no listeners are bound to the error event, the error will be printed to the console.

idle

idle: MapLibreEvent

Fired after the last frame rendered before the map enters an "idle" state:

• No camera transitions are in progress
• All currently requested tiles have loaded
• All fade/transition animations have completed

load

load: MapLibreEvent

Fired immediately after all necessary resources have been downloaded and the first visually complete rendering of the map has occurred.

• Add live realtime data
• Animate a point

mousedown

mousedown: MapMouseEvent

Fired when a pointing device (usually a mouse) is pressed within the map.

See

Create a draggable point

mousemove

mousemove: MapMouseEvent

Fired when a pointing device (usually a mouse) is moved while the cursor is inside the map. As you move the cursor across the map, the event will fire every time the cursor changes position within the map.

• Highlight features under the mouse pointer
• Display a popup on over

mouseout

mouseout: MapMouseEvent

Fired when a point device (usually a mouse) leaves the map's canvas.

mouseover

mouseover: MapMouseEvent

Fired when a pointing device (usually a mouse) is moved within the map. As you move the cursor across a web page containing a map, the event will fire each time it enters the map or any child elements.

• Get coordinates of the mouse pointer
• Highlight features under the mouse pointer
• Display a popup on hover

mouseup

mouseup: MapMouseEvent

Fired when a pointing device (usually a mouse) is released within the map.
